The interview was quite good. The first round was with the hiring manager, which I cleared with very strong hire feedback. Then there was a UML system design round, from which I got positive feedback from the interviewer. However, after two days, I received a rejection email.

I don't know the reason behind that rejection, but it was not due to my performance at all. So, I feel that even if you excel in all rounds, there is a very low probability that you will be hired. It was a very bad experience in terms of evaluations.

Oops, concepts, design patterns, and all in hiring manager. Then UML system design, which was kind of easy to medium level.
